ABSTRACT:
A roller type fixing unit for a copying machine which has an opening and closing frame part or lid also has a pair of rollers for thermally fixing a thermoplastic toner image on a sheet. A link mechanism transmits and multiplies the force required to close the frame part or lid to a movable lever which forms a part of the link mechanism. The movable lever supports one of the rollers and presses it against the other roller when the frame part is closed. When the frame part is opened, a spring biases the movable lever so that the roller which it supports is moved away from the other roller. Thus, a jammed sheet can readily be removed from the copying machine.
